cable to apparatus for dispensing soda-water, wherem the same valve mechanism controls the delivery of the flavoring-syrups and the delivery of carbonated water.

Our invention provides valve mechanism which is absolutely liquid-tight, to selectively control the flow of difierent syrups from a plurality of receptacles, to dispense a definite amount of the selected syrup, to control the flow of the carbonated water, and to mix said water with said quantity of syrup within said valve mechanism and discharge said mixture.

As hereinafter described, our invention comprises a main valve mechanism arranged to selectively control the delivery-ports of a plurality of syrup-receptacles, combined with an auxiliary conical valve-plug and a casing comprising a conical seat for said auxiliary plug, said auxiliarylug casing comprising a duct and said a iary plug comprising a plurality. of ducts arranged to register with the duct in said casin a cap arranged to adjust said auxiliary plug to its seat, and bearlug-balls between said plug and cap.

Our invention comprehends the variou novel-features of construction and arrangement hereinafter more definitely specified.

In the accompanying drawings, Figure I is a side elevation of a. soda-water apparatus conveniently embodying our improvements. Fig. II is a front elevation of the valve mechamsm shown, in Fig. I.

In said figures the frame 1, having the legs 2, conveniently supports a plurality of removable syrup-receptacles 3 and a removable ice-container 4, which latter is provided with the water-outlet spigot 5 and removable lid 6.

The valve mechanism is conveniently suspended beneath said frame 1 by the hangers 7 and 8 and comprises the main casing 10, having the rear end ca p ll secured therein by set-screws 12 on opposite sides of the casmg, and the plurality of syrup-ports 13, 14, 15, and 16, respectively connected to separate syrup-receptacles 3 by the pipes 17, 18, having a stop-cock 21.

There are two .of said pins 27, one of'which is shown in. Fig. III, and both pins are carried by the plug 25 and extend in sockets in the cap 11 in registry with res ective screws 26.

The sleeve 38, having the operatin -handle 39, is interposed in rotary relation etween the stationary plug 25 and its casing 10 and is provided with a plurality of apertures 42, 43, 44, and 45, arranged-in diagonal relation on its circumference to register with the res eotive 'ports 13, 14, 15, and 16. Said s eeve 38 may be turned to brin any one of said apertures into registry with its respective port in said casing 10 by tilting said han- 3 plug by the spring-washer 62, held under compression b the nut 63 on the threaded dle 39 into opposition to the numeral indii cated on thediabplate 46 in Fig. II, corresponding tothe port for the desired syrup. Said sleeve 38 is preferably provided with a coverin 40, of any suitable material, such as hard rubber, to prevent the corrosive action usual in syrup-controlling valves. The extreme positions'of said sleeve 38 (designated by the numerals 1 and 4 on said plate 46 and respectively corresponding with the operative position of the apertures 42 and 45 in the sleeve 38) are determined by the lug 48, projecting from the end plate 49 on said sleeve 38 and arranged to encounter the ends 50 and 51 of the recess 52 in the casing 10. (Best shown in Fig. II.) The main rotary plug 55 is mounted in eccentric relation within said stationary plug 25 and comprises the measuring and mixing chamber 56, having the inlet-aperture 57, arranged to register with the a erture 30 in said stationary plug 25, and the ports 13, 14, 15, and 16 in said casing 10 and the outlet-aperture 60, arran ed to register with the outlet-aperture 32, eadin to the discharge-nozzle 33. Said rota-r p ug 55 is maintained in its seat in sai stationary stem 64 of sai rotary plug, and it is limited in its rotary movement the collar 65,fitted to the squared portion 6 of the stem 67, which carries the handle 68 of said plug 55, said collar being provided with the lug 70, arranged to engage the shoulders 71 and 72 on the end of the stationary plug 25. Said rotary plug 55 is provided with the air-outlet passage or vent 75, leading from said mixingchamber 56, extending circumferentiall on the periphery of said rotarly plug 55 and aving the extension 76 paral el with its axis arranged to re ister with the outlet 32 in said stationary C ip ug 25. Said rotary plug 55 is also provi ed :with the carbonated-watermixing duct 80, leading through its threaded stem 64 into the mixing-chamber 56, and the 'carloonated-water-jet duct 82, leading through said threaded stem 64 and chamber 56 to the carbonated-water chamber 83, which latter has the outlet-jet duct extending through the wall of said rotary lug 55 and arranged to register with the a oresaid jet-outlet 35 in the stationary plug 25.

The auxiliary conical valve-plug 90, having the ducts 91 and 92, is adjustably secured to the threaded stem 64 of said main rotary plug 55 by the adjustable nut 94 and the jam-nut 95, arranged to engage the end of said threaded stem 64 within the socket 93 in said auxiliary plug 90.

In order to insure that the ports 91 and 92 shall register in liquid-tight communication with said ducts 80 and 82, the former are provided with the nipples 96 and 97, arranged to be telescoped within the latter.

The auxilia casin 100, having the cou= ical seat 101 ?;1 said auxilia p ug 90, is provided with the duct 102 an port 103, arranged to register with either of said ports 91 and 92 to deliver carbonated water from any desired source of supply connected with said casing b the conduit 104. Said valveplug an casing are adjusted in proper. relation by the cap 105, which is in screw-threaded engagement with said casing 100 and secured by the iam-nut 106, and we find it desirable to provide the bearing-balls 107 between the plug 90 and the cap to permit free rotary movementof said plug 90 when its conical surface is in liquid-tight contact with its conical seat 101.

Said apparatus may be operated as follows: Both handles 39 and 68 being normally in vertical osition, when it is desired" to dispense so a-water of a selected flavorfor instance, the flavor contained in the receptacle which communicates with the port 15'the handle 39 is turned to the left with reference to Fig. II until it registers with the numeral .-2 on the plate 46, and the aperture 44 in the sleeve 38 will then register with said port 15.

The handle 68 is then turned to the left with referenceto Fig. 11 to the horizontal position indicated by dotted lines in Fig. II, so that the aperture 57 in the plug 55 registers with said port 15, and the air-vent 75 is in communication with the outlet-aperture 32 to permit the escape of air from the chamber 56 while the latter is being filled with the selected syrup, although the outlet-aperture 60 is 7 When the desired amount of syrup has been admitted to said chamber 56, the handle 39 is .turned to its normal vertical position and the handle 68 is turned to the osition shown in full lines in Figs. 11 and H to establish communication between the carbonatedwater port 103 in the auxiliary casing 100 and the mixing-chamber 56, so that the carbonated water flushes said chamber under pressure and mixes with the syrup, the mixture being thus discharged through the apertures 60 and 32, which are then in registry. The carbonated-water-jet nozzle 36 is then brought into communication with the carbonated-water-inlet port 103 in the casing 100 by turning the handle 68 to the horizontal position indicated in dotted lines at the rightand side of Fig. 11 until the desired amount 'of carbonated water has been delivered. The handle 68 is then turned to its normal- (Shown in dotted lines in Each receptacle 3, being remov- Fig. 11.)
